Is It Possible to Run Multiple UI Automation Processes Using High-Density Robot on the Same Machine with Different Sessions?

I would like to know if it is possible to run multiple UI automation processes using a High-Density Robot on the same machine with different user sessions. The goal is to execute multiple unattended processes simultaneously without conflicts.

Please advise on the best practices, configuration steps, and any potential limitations for running concurrent UI automation processes on a single machine.

Looking forward to your guidance

Yes, it is possible to run multiple UI automation processes using a High-Density Robot on the same machine with different user sessions in UiPath. High-Density Robots allow you to run multiple automation processes on a single machine by leveraging different user sessions, and they are designed to help organizations optimize the use of their physical machines.

Key Points on High-Density Robots:

  • Multiple Robots per Machine: A High-Density Robot allows you to run multiple robots on a single machine by associating each robot with a different user session.
  • Different User Sessions: Each robot runs in its own user session, ensuring that each automation process has its own dedicated environment and does not interfere with the others. This is especially useful when you need to run multiple unattended processes simultaneously on a single machine.
  • Licenses: Ensure that you have sufficient licenses for the number of robots you want to run. UiPath offers different types of licenses for High-Density Robots, so ensure your license covers the desired number of concurrent robots.

Hi @logesh_kumar1

Yes, it’s feasible to run multiple UI automation processes simultaneously on a single machine using High-Density Robots. Set up each robot with distinct user sessions in Orchestrator. Ensure each session has adequate system resources (CPU, RAM) and that there’s no session overlap or UI element conflicts. Proper session isolation and resource management are key.

Thanks for the answers! From what I read in the documentation, UI automation using hardware events may not be possible, which left me confused. So, is it possible to run automation that involves UI automation with hardware events?

Great @logesh_kumar1

You’re right—hardware events may not work with High-Density Robots due to session isolation. Instead, use activities like Click, Type Into, and avoid relying on hardware events, or consider RDP/Citrix for event simulation across sessions.
